Specification of Letters Patent.

OAR-WHEEL.

Patented Oct. 30, 1906.

Application tiled May 19, 1906. Serial No. 317.700.

of the invention being to provide a wheel of suoli construction that even under the most adverse conditions of operation itshall last for a relatively long time and reduire but little attention, the arrangement-of parts being such that the only portion of the wheel subject to appreciable weai, may be easily removed and replaced.

Another object of my invention is to prevent wear of the hub, as well as ofthe axle, by the use of a chilled-iron bushing within said hub, and, moreover, I desire to so support the car-axle that it shall be free to vturn under certain circumstances, thereby preventing localized wear on but yone portion thereof. In addition I provide an vopening for the introduction of oil to the interior f the hub, so placed as to be always. accessible for the reception ofthe spout of an oil-can irrespective of the position ,of the wheel on its axlc,'and also provide improved means for excluding dirt, water, ac., from the oil-hole and from the inner. end of the hub-bushing.

The above objects and other advantageous ends I secure `as hereinafter set forth, reference being had to the accompanying drawings, in which- Figure l is a side elevation of a wheel constructed according to my invention.- Fig. 2

. is a'vertical section taken on the line 2 2, Fig.

l. Fig. 3, is a partial horizontal section of the wheel, taken on the line 3 3, Fig. l. Figs. 4 and 5 are vertical sections taken on the lines 4' 4 and 5,5, respectively, Fig. 2; and Figs. 6 and `7 are respectively a plan and a side elevation of the pedestal. v

In the above drawings, A representsv the body or main portion of the wlieel,having la rim afarmse, and a hub c2. This hub ,is

partially cored and partiallybored for the" reception of a bushing or sleeve B, of (',hillml iron which-is. closed-at its outer or forward end and has an annular recess at its opposite end for-thc reception of a ring or washer I),

of fibrous material, for'preventing passage ,of oil or the entrance of dirt, &c., between the car-axle() and said bushing. This latter is provided with an annular flange b', and through. this extend bolts a3, which also pass through suitable holes in the hub of the wheel. The heads of these bolts fit into square recesses in the flange, and the nuts on their opposite ends are kept from backing ,l

oil' bynieans of portions of washers fr, which are turned up to engage the sides of said nuts after these latter have been set u In addition to having a numffer of openings or ports b2 to permit-of the assage of oil from the hollow interior of the liub to the axle C, the bushing B has a slot b3 for the reception of a forked key b4, designed to fit into an annular recess cformed in said axle. A iiber washer b5 is also placed in a suitable recess, usually at the base fof the flange b, to

prevent passage of oil between the bushing B and the adjacent vertical face of the Wheel A.

To permit of the introduction of oil to the hollow interior of the hub a3, I provide an opening ai in the center of the end thereof coaxial with the axle C, keeping this normally closed by means of a leather washer a, held in positionby a flat spring (1,7,whose ends project into recesses within the hub and which is held in place by the end portion of the sleeve or bushing B; The body of the ear is indicated at E with one of the pedestals D, which is preferably of ,the construction shown in Figs. 6' and 7, and held to said car-body on bolts e'. Y

In assembling the parts of this device after the fiber washer b has been placed in its recess in the sleeve B this latter is slipped over the end of the axle C and the forked keyb is dropped through the slot b3 therein, so that its ends enter the annular recess c of said axle. This key is retained in place bythe wheel A, for when this is placed on the sleeve B -its bored portion completely covers the slot b3.

IThe nuts on the bolts c are then set up and v the washers a4V bent. so as to prevent their turning inthe future. sleeve is vof chilled iron its wear is very vcon- Sicv IOO

Inasniuch as said siderably` less than that ofthe ordinary castiron hubs hitherto used in wheels of the saine general type, and it is further to be noted that after such Wear has occurred to what is considereda serious extent it is possible to very conveniently and quickly remove the Worn sleeve and replace it by a new one.

Uhder'ncrmal conditions the fiat spring a7 keeps the leather disk a tightly pressed against the openingc5 oi the hub, so that sand, Water, &c., are effectually excluded from the oil-chamber. It is also impossible ior such substances to obtain access at the opposite end of the Wheel-hub because of the Washers and b5.

When it is desired to supply oil to the interior of the hub, this may be done by introducing the nozzle of an oil-can into the opening 0,5, thus temporarily moving the washer c out of the Way. Vhen the can is removed, the spring c7 again forces said washer into its former position.

The axle C is free to turn in the pedestalbearing d, so that there is no danger of its .Wearing unevenly, as would be the case if it was innnovably held.

I claiml. The combination of a wheel having a chambered hub, an axle therefor, and a bushing'of chilled iron in the hub of the wheel for the reception of the axle, there being a dirtexcluding ring between the bushing and the hub, substantially as described.

2. The combination of a wheel having a cored hub, an axle for the Wheel, a bushing closed at the end and fitting over said axle, said bushing bcing'iremovably fixed in the hub and having an opening or openings to permi't of the passage of oil from the hub to the axle, substantially as described.

3.' The combination of a wheel having a hard-metal bushing removably iitted to .its hub, an axle projecting Within said bushing, a relatively lixe'l bearin'g for the axle, and a dirt-excluding ring between the axle, the bushing and the bearinv, substantially as described. I

4. The'combination of a wheel having a hollow -h'ub closed on one face, a 'flanged bushing fitting into the hub frein the op osite face thereof, a dirt-excluding rin etween the flange and the hubfan axle within saidbushing, means forl normally preventing removal of the wheel andthe bushing from said axle, with a bearing, and a second dirtexcluding ring between the said bearing and the adjacent'p'ortion of the bushing, substantially as described.

5.,'The'combination of an axle having an annular groove, albushing having a slot placed to register with said groove, a key in the slot extending into the groove of the axle, with a Wheel removably fitted to the bushing and normally retaining the key in its slot, substantially as described.

6. rl'he combination of a wheel having a cored hub made with a bored portion, a bushing of relatively hard metal removably fitted tothe bored portion of the hub and having a slot normally covered thereby, an axle having an annular groove placed to register with said slot, and a' key in the slot having portions extending into the annular groove of the axle, substantially as de scribed. 4

7. The combination With the body of a car, oi" a pedestal therefor, an axle bearing in said pedestal, a hardened-metal bushing for the axle, said bushing being closed at one end and having a dirt-excluding rin between itself and the pedestal at the oppos1te`end, radially-projecting portions on the bushing, with a wheel mounted on the bushing and bolts removably connecting the rejecting portions of the bushing and said wllieel, substantially as described. 'y

8. The combination of a wheel having a chambered hub closed at one end,with an axle extending into said hub, there being an opening in the hub concentric with the axle, and a yieldingly-supported cover for said opening, substantially as described.

9. The combination of a wheel having a chambered hub and an axle extending into' the same, there being an opening in the hub substantially concentric with the axle, a bushing within the hub, a cover for said opening into the lmb, and a spring mounted between the bushing and said cover for normally maintaining the saine in position, substantially as described.

10. The combination of a Wheel having a chambered hub and an4 axle extending into the same, there being an opening in the hub concentric with the axle, a bushing Within the hub, a piece for closing said opening into the hub, and a flat spring guided within the hub and attached to said piece for closing the hole, said bushing engaging the s ring t0 maintain it in position, substantial y as described.

In testimony whereof I have signed my name to this specification in the presence of 4two subscribing witnesses.
